When you click the edit button to change your email a little window will appear. Type the new email address in that window and click continue. A new window will appear and an email will be sent to the email address you typed in the screen before. In that email will be a code to enter.

A few questions to ask yourself... Is the email address you entered the new email address? Are you able to access that email address yet to check for the new message? Are you typing the correct email address?
